Photo: Shutterstock<\/p>\nA casual peace sign in a selfie has become China\u2019s latest online privacy concern after experts warned that the popular pose could expose users\u2019 fingerprints.<\/p>\n
In a mainland workplace reality show aired in April, financial expert Li Chang used a celebrity selfie to show how clearly visible fingers in a photograph could put personal biometric data at risk.<\/p>\n
Li said fingerprints could potentially be extracted from selfies taken within 1.5 metres if the fingers faced the camera directly. Even at a distance of 1.5 to 3 metres, around half of the hand details could still be recovered.<\/p>\n
The programme showed fingerprint ridges becoming visible after the image was enhanced with photo-editing software and artificial intelligence (AI) tools.<\/p>\n
According to China Newsweek, Jing Jiwu, a cryptography professor at the University of Chinese Academy of Sciences, said portrait photos taken with high-quality cameras could make it possible to reconstruct hand details from a \u201cscissor hand\u201d pose.<\/p>\n

He noted that fingerprint recovery was usually difficult due to factors such as lighting, focus and image clarity. However, the risk increases when photographs are taken with higher-resolution devices or when criminals obtain multiple related images.<\/p>\n","protected":false},"excerpt":{"rendered":"A casual peace sign in a selfie has become China\u2019s latest online privacy concern after experts warned that…\n","protected":false},"author":2,"featured_media":477170,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[74],"tags":[291,1307,289,1423,798,208974,3901,109352,5190,435,153032,381,5214,55636,79632,2006,4737,715,208979,982,3785,2594,15168,124442,54343,40177,18,2007,208975,36962,85439,1943,208983,846,208973,208982,19418,208985,12668,23695,27127,188887,2598,4596,19,202769,208980,17,20585,62816,47086,1109,7219,208986,32877,11723,44497,12817,208978,208981,824,76346,17500,208976,172,523,32228,11986,9588,208977,14614,85595,827,2792,12368,12443,208984,50444,53051,57274,5570,864,190029,1799,753,82,1238,1817,3551,95146,128,13563,17752,124675,836,53971,52497,40351,8972],"class_list":{"0":"post-477169","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-ai","9":"tag-apps","10":"tag-artificial-intelligence","11":"tag-attendance","12":"tag-beauty","13":"tag-biometric","14":"tag-blur","15":"tag-calls","16":"tag-camera","17":"tag-celebrity","18":"tag-centre","19":"tag-china","20":"tag-chinese","21":"tag-clarity","22":"tag-cloning","23":"tag-company","24":"tag-concern","25":"tag-crime","26":"tag-criminals","27":"tag-cybersecurity","28":"tag-dark-web","29":"tag-data","30":"tag-devices","31":"tag-difficult","32":"tag-documents","33":"tag-editing","34":"tag-eire","35":"tag-employee","36":"tag-enhanced","37":"tag-experts","38":"tag-exposes","39":"tag-facial","40":"tag-filters","41":"tag-financial","42":"tag-fingerprints","43":"tag-fists","44":"tag-focus","45":"tag-forged","46":"tag-fraud","47":"tag-habits","48":"tag-hand","49":"tag-high-quality","50":"tag-home","51":"tag-identity","52":"tag-ie","53":"tag-illegally","54":"tag-impersonate","55":"tag-ireland","56":"tag-leaked","57":"tag-lighting","58":"tag-lock","59":"tag-media","60":"tag-online","61":"tag-palm-reading","62":"tag-peace","63":"tag-phone","64":"tag-photographs","65":"tag-portrait","66":"tag-pose","67":"tag-posting","68":"tag-privacy","69":"tag-professor","70":"tag-reality-show","71":"tag-reconstruct","72":"tag-research","73":"tag-risk","74":"tag-risks","75":"tag-scam","76":"tag-sciences","77":"tag-scissor","78":"tag-screen","79":"tag-selfie","80":"tag-services","81":"tag-shanghai","82":"tag-show","83":"tag-sign","84":"tag-silicone","85":"tag-slimming","86":"tag-smart","87":"tag-smooth","88":"tag-social","89":"tag-software","90":"tag-suspicious","91":"tag-system","92":"tag-tech","93":"tag-technology","94":"tag-television","95":"tag-test","96":"tag-theoretical","97":"tag-tools","98":"tag-tv","99":"tag-university","100":"tag-variety","101":"tag-victims","102":"tag-video","103":"tag-visible","104":"tag-voice","105":"tag-warned","106":"tag-workplace"},"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/477169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=477169"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/477169\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/477170"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=477169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=477169"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=477169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
